So far I’ve designed the crappy-but-it-works version! It looks gross, I’ll be honest. My intention was to make the project as off-the-shelf as possible, but I think that in order for it to function to its full potential it will need some custom parts. I’m gonna 3D print a few parts, but I’m also going to work out some alternatives for people without access to 3D printers.
My next steps are to run a test of the purifier, but before that I’m going to get a little handheld water tester and see if I can hack the sensors to work with an Arduino. Actual “Scientific” instruments are way to expensive for me to use in this project or expect someone else to get, so I’m going to try and find a workaround. Theoretically the sensors themselves aren’t impossible to make myself, but it would be muuuuuuuuuuch easier to buy some.
